Be it known that I, ERASTUS \VOOD\VARD,

of So1nerville,i n the county. of Middlesex and State of Massachusetts, have invented certain new and useful Improvements 'in Tack-Driving Machines, of which the following, taken in connection with the accompanying drawings,'is'a specification.

The improvements are involved in several devices which may he bestunderstood 'b y ref- I erenee to the description in connection with theacconipanying drawings in which- Figure 1 is a side elevation.

To limit the back and forth swinging motion of the jack, a'supplemental forked piece H' is used; This is piv-' oted on the swiveling tumbler H and terminates in forked ends h, 71, (see Figs. 16 and to swingfreely'in'a .ve'rti- 1'2} which, when the jack is tipped too far forward, will comei'n contactwith the under side of a cross-bar H which forms a portion of the jack foot-piece H and this checks further mot-ion in this direction.

be seen by an inspection of the drawings, In

order to limit the back and forth motion of the jack I have a set screw H inthe top part of thesupplemental forkedpiece H, which abuts against the piece H 4, forming a part of the forked piece 11"., H l, This limits the forward motion, and thel set sc'rew ll in the piece H abutting against the upper part of thejack foot-piece HF limits the rearward mo tion.
